SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 720,673, dated February17, 1903.

Application filed March 25, 1902. Serial No. 99,871. (No model.)

To all whom it may concern.-

Be itknown thatI, J ERREY W. COLLINS, of Sherrill, in the county ofOneida, in the State of New York, have invented new and usefulImprovements'in Snap-Hooks, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention relates to. improvements in snap hooks, technically knownas a snap, adapted for various purposes for which a detachable lock orconnection is required.

One of the objects of this invention isto simplify the constructionand-to thereby-reduce the cost of manufacture and at the same time toproduce a snap which is durable and efficient in use, another objectbeing to construct the snap with as few parts as possible.

To this end the invention consists in the combination, construction, andarrangement of the parts of a snap-hook, as hereinafter fully described,and pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation, partly insection, of a snaphook embodying the various features of my invention.Fig. 2 is an end elevation of the snap seen in Fig. 1. Figs. 3 and 4 aresectional views taken, respectively, on lines 3 3 and 4 4, Fig. 1. Figs.5 and 6 are side elevations of slightly-modified forms of my invention,the sleeve in Fig. 5 being in section. Figs. 7 and 8 are sectional viewstaken, respectively, on lines 7 7 and 8 8, Fig. 6; and Fig. 9 is aperspective view of a further modified form of sleeve.

Similar reference characters indicate corresponding parts in all theviews.

In the drawings, Figs. 1 to 4, inclusive, I have shown a snap consistingof a bar 1, a

sleeve 2, and a spring 3, the bar 1 terminating at one end in a hook 4,and its other end is returned or bent upon itself for forming a guidebar or extension; 5, which is arranged substantially parallel with themain body of the snap, the junction of the extension 5 with themain bodybeing arranged to form an eye 6, which is adapted {to receive a suitablepivotal pin or screw for fastening the snap to any desired article withwhich it may be used. This snap may be used for any desired purpose,such as a gate-hook or look for the lids of receptacles, the eye 6 beingadapted to receive any form of fastening means, such as a staple orbolt, upon which the snap may readily swing. It is evident, however,that this eye 6 may be elongated, as seen in Figs. 6 and 7, to receivethe strap or other portion of a harness, or the snap may be used inconnection with the links of a chain for various purposes. The hook4forms a continuation of the bar 1, and although I have shown said hookas adapted for a gate or lid lock it is evident that this hook may beotherwise formed and maybe bent in the form of an eye, as seen in Figs.5 and 6. The intermediate portion of the main body of the bar 1 isformed with a lug 7, which is stamped or pressed outwardly from thestock forming the main body and is adapted to hold the sleeve 2 fromrotation in any desired manner, hereinafter de scribed. This sleeve 2 ispreferably formed from a single piece of sheet metal, one end beingcrimped or partially closed at 8 for forming an abutting face adapted toabut against the free extremity of the hook 4, said inwardly-crimped orpartially-closed end also forming ashoulder, which forms a convenientseat for one end of the spring 3. The other end of the sleeve is adaptedto receive the extension 5 and is reciprocally movable thereon, beingprovided with a slot 9, which receives the lug 7 and prevents therotation of the sleeve, this slot being of sufficient length to permitthe sleeve to bemoved endwise toward and away from the free extremity ofthe hook 4. This sleeve is bent in the form of a cylinder, and itsmeeting edges are provided with outwardly-proj ectinglu gs l0,which forma convenient handpiece, whereby the sleeve may be moved endwise againstthe action of the spring 3, as in the act of opening the snap. Thisspring is inserted in the sleeve, one end being seated against thecontracted end 8 of the sleeve, and is tensioned to normally force thesleeve into contact with the free end of the hook for closing the loop.

It is evident from the foregoing description that the main body,extension 5, hook 4, and eye 6, as well as the In g 7, are all formedfrom a single piece of wire and that the sleeve 2, shoulders 8, and lugs10 are formed from a single piece of sheet metal, thus forming asnap-hook with only three partsthe bar 1, sleeve 2, and spring 3Whichare economically manufactured,are readily assemb1ed,and form a durableand efficient snap.

In Figs. 5 to 8, inclusive, I have shown a snap consisting of a mainbody 11, terminating at one end in a hook 12, the opposite end of saidmain body being returned upon itself for forming an extension 13, thefree end of the hook and said extension being in substantial alinementwith each other, and the extension, Fig. 5, having a lug 7 entering aslot 9 in the sleeve.

In Figs. 6 to 8, inclusive, I have shown a slightly-modified form ofsleeve 14, which is formed from a solid piece of metal drilled inwardlyat one end a part of its length for forming a socket 15 and a closed end16, a suitable spring 17 being arranged in the socket between the endface of the extension 13 and the closed end 16, said spring beingtensioned to force the closed end against the end face of the freeextremity of the hook 12. This modified form of sleeve is provided witha lateral extension 18, which is provided with an eye 19 to receive themain body 11 of the snap and forms an additional guide to prevent therotation of the sleeve upon the extension 13, this extension alsoserving to additionally hold the sleeve in operative position.

In Fig. 9 I have shown a sleeve 14, adapted to he used on the extensionseen in Figs. 6 to 8, inclusive, said sleeve being formed from a singlepiece of sheet metal and provided with wings 18, stamped outfrom thebody of the metal and adapted to lie upon the main body 11 of the bar toprevent rotation of the sleeve.

The operation of my invention will now be readily understood uponreference to the foregoing description and the accompanying drawings,and it will be noted that some change may be made in the detailconstruction and formation of the parts of the snap Without departingfrom the spirit thereof. Therefore I do not limit myself to the preciseform and arrangement shown and described.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, isl 1. A snap-hook comprising arms rigidly united atone end, one of the arms terminating in a hook, a split sleeve slidableon the other arm and having portions of its meeting edges bent outwardlyfor forming a handpiece.

2. A snap-hook comprising arms rigidly united at one end, one of thearms terminating in a hook, a split sleeve slidable on the other arm andhaving its meeting edges formed with outturned lugs for the purposedescribed and a spring within the sleeve and acting to force the sametoward the end of the hook.

3. A snap-hook comprising arms rigidly united at one end, one of thearms terminating in a hook, a sleeve slidable lengthwise on the otherarm and having one end partially closed and adapted to abut against theend of the hook, and a spring acting to close the sleeve against saidhook.

4. A snap-hook comprising a continuous bar terminating at one end in ahook and having an intermediate fin, the other end being bent toward thehook, a longitudinally-movable sleeve guided on said other end andprovided with a slot receiving the fin for the purpose set forth.

5. A snap-hook comprising abar terminating at one end in a hook andhaving its other end bent back upon itself, a sleeve mounted on thelatter end and movable end wise toward and away from the hook, saidsleeve having a lengthwise slot, a fin on the bar projecting into theslot, and a spring acting on the sleeve to force it toward the hook forthe purpose set forth.

6. A snap-hook comprising a bar terminating at one end in a hook andhaving its other end bent back upon itself, a fin stamped out from theintermediate stock of the bar, a sleeve encircling the latter end of thebar and movable endwise toward and away from the hook, said sleevehaving a lengthwise slot receiving the fin, and a spring acting againstthe sleeve to force it toward the hook for the purpose described.

In witness whereof I have hereunto set my hand this 19th day of March,1902.
